Interface IBaseDataSetProcessorWithDBSave

These processors automatically integrate with the LemonEdge IEntityUpdater.SaveChanges(System.Threading.CancellationToken, bool, System.Data.Common.DbTransaction) operation

Any custom processes that you want to run during a save process can be integrated using this interface and custom IBaseDataSetProcessor functionality

The system uses this for enforcing processes on save such as some of the transaction engine functionality like cancel/correct technology

Properties

Order

If we have multiple save processors working, this indicates the order in which they will be processed with relation to each other

Declaration
short Order { get; }
Property Value
Type Description
short

SaveProcessed

Indicates the ProcessOnDBSave has already been run. This is set by the system during save, and prevents recursive calls.

It is also released by the system on save completion/failure

Declaration
bool SaveProcessed { get; set; }
Property Value
Type Description
bool

Methods

ProcessOnDBSave()

Will only run when connected to the database directly.

i.e. in the web service or in a client connected to the db service, not in a client connected to the web service.

For the client connected to the webservice, as part of the webservices save routine it will call this.
Declaration
Task ProcessOnDBSave()
Returns
Type Description
Task

RollbackChanges()

During process on db save, the context can be left in an inconsistent state if it fails any validation. This is called if the transactional save failed and the context must be put back to a consistent state similar to before ProcessOnDBSave was called.

Most processors are fine running again after a failed transaction save has been fixed by the user.

However some require work to be undone such as cancel/correct objects being created for transactions. The cancel/correct transactions need to be removed.
Declaration
Task RollbackChanges()
Returns
Type Description
Task
Remarks

When running in a service this will be disposed of anyway, it is only relevant for when the client is directly connected to the database server.
